YARN OR THREAD GUIDE FOR SPINNING 0R TWISTING MACHINES.

Specification of Letters Patent.

Application filed September 29, 1909.

Serial No. 520,177.

To all whom it may concern:

'Be it known that I, ISAAC E. PALMER, a citizen of the United States, residing at Middletown, in the county of Middlesex and State of Connecticut, have invented an Improvement in Yarn or Thread Guides for Spinning or Twisting Machines, of which the following description, in connection with the accompanying drawings, is a specification, like numerals on the drawings representing like parts.

This invention relates to yarn or thread guides for spinning or twisting machines. In order that the principles thereof may be readily understood, I have disclosed a single type thereof in the accompanying drawings, wherein- Figure 1 is a side elevation of a yarn or thread guide embodying my invention and representing the same in one selected position of adjustment with reference to the delivery rolls; Fig. 2 is a similar view of the guide in a slightly different adjusted position with respect to said delivery rolls; Fig. 3 is a cross section upon the line- 33 of Fig. 1; Fig. 4 is a vertical section upon the line 44 of Fig. l; and Fig. 5 is a View similar to Fig. 3 of a slightly modified form of my invention.

In accordance with my invention I provide a yarn guiding member, preferably of disk form having a yarn or thread conditioning periphery, this disk or member being suitably supported and provided with means whereby the extent of peripheral engagement of the yarn or thread therewith may be varied, thereby to vary the conditioning action of the guide upon the thread or yarn. The guide when used in the treat-- ment of yarns is interposed between the delivery rolls and the spindle, so that the yarn in its spinning action is twisted or rotated axially upon the conditioning periphery of the disk or member, the described axial twisting of the yarn extending from the spindle substantially to the delivery rolls. In using the thread guide in the formation of thread, the guide is similarly positioned so that it may axially twist over the periphery thereof. Preferably the means for varying the peripheral engagement of the yarn or thread with the disk is a second disk likewise provided with a yarn or thread receiving and conditioning periphery.

Referring more particularly to the drawing, the frame of the thread guide is indicated at 1 in the several figures, it being preferably provided with a slot 2 at the rear end permitting it to be mounted upon the clapper of a spinning machine or other part with capacity for longitudinal and lateral adjustment, as, for example, by a bolt and washer. The frame 1 is represented as opened at its front end for the admission of the yarn or thread, and to that end I may provide spaced ears 3, such as shown in Fig. 3. Said ears may be of any suitable contour and may be provided with means such as indicated at 4E L in Fig. 5 to prevent the escape of the yarn or thread from the guide.

While the frame 1 is herein represented as made in a single piece, it is apparent that it may be longitudinally divided and secured together in suitable manner.

Between the forward parts 5-5 of the side members of the frame 1, I position a yarn guiding member 6 preferably in the form of a disk having a grooved periphery. While said disk may be rotatable, preferably it is clamped or otherwise held from rotation, as by means of a screw 7 passing through the portions 55 of the frame and said disk, as clearly represented in Fig. 4.

The delivery rolls of a spinning machine are represented at 88 in Figs. 1 and 2, the yarn 9 issuing therefrom and passing over the disk 6 to the spinning spindle. I provide suitable means to vary the peripheral engagement of the yarn or thread 9 with the disk 6, in order to alter or adjust the conditioning action of the disk 6 upon the yarn or thread. While for this purpose I may employ any suitable means, I preferably provide a second disk represented at 10 in Figs. 1, 2 and 4. Preferably I support or mount the said disk upon the frame 1, and for that purpose have herein provided a supplemental frame consisting of the arms 1111 pivoted upon the screw 7 and provided at their outer ends with a screw 12 passing therefrom and axially through the disk 10, so as to support the same in the manner indicated. Preferably the disk 10 is held from rotation. Any suitable means may be employed to adjust the disk 10 angularly with respect to the disk 6 and to that end the screw 7 may be sufficient for the purpose. Preferably, however, I provide supplemental or other means herein consisting of arcuate slot 13 in one of the arms 11 and position therein a screw 14:, by

which the arms 10 when adjusted may be clamped in position.

The disks 6 and 10 may be and preferably are solid, but I may substitute a divided disk 1515, as indicated in Fig. 6, each part thereof having teeth 16-16 to provide yarn cleaning or clearing projections.

It is apparent that by adjusting the position of the parts from that shown in Fig. l to that shown in Fig. 2, the extent of peripheral contact of the yarn or thread with the disk 6 as well as with the disk 10 is increased. The disk 6 and preferably the disk 10 serves to condition the yarn or thread during the spinning or twisting operation. If the said disk or disks have smooth peripheries, they serve to round up orsmooth the yarn or thread, and if they be provided with clearing surfaces, such, for example, as indicated in Fig. 5, they remove more or less of the protruding fibers or fluffy portions of the yarn, lumps and foreign matter. It is apparent that either one or both of the disks 6 and 10 may be provided with clearing or cleaning surfaces, such, for example, as indicated in Fig. 5, and that by adjusting the parts the extent of this clearing action may be varied.

While the disks 6 and 10 may be arranged at any suitable distance apart, preferably they are closely adjacent so as to permit effective action thereby upon the yarn or thread as it is passed between and about them.

Having thus described one illustrative embodiment of my invention, I desire it to be understood that although specific terms are employed, they are used in a generic and de scriptive sense and not for purposes of limitation, the scope of the invention being.

set forth in the following claims.

Claims.

1. A yarn or thread guide for spinning or twisting machines comprising a frame having opposite side members, a disk positioned between and supported by said members and having a yarn or thread guiding and conditioning periphery, a second disk supported by said frame above the first disk and having a yarn or thread guiding and conditioning periphery laterally alined with that of the first disk, and means to permit adjustment of said second disk in an arc about the axis of said first disk as a center.
